while constructed to close the opening formed by thedoor frame, areconstructed in such a manner that there is always considerable spacebetween the base of the door frame and the base of the door. Usually thedoor latch is suificient to hold the door firmly in closed positionduring the early life of the car but rattling of the doors invariablydevelops after a short while. Various methods have been employed toavoid this rattling, such as the employment of buffer members on theside .of the door or door frame, these buffer members constituting anyconvenient device which might be ready to hand such as thin sheets ofrubber,

' projecting rubber knobs and the like, which have been employed withindifferent success and readily wear in no time. In order to overcomethe difficulty it is necessary to provide a device of extremely simple.construction, of wear resisting character and positioned in a manner tocontact firmly withthe door and to the best advantage.

stances.

A further object of the invention is to provide a device which willpermit suflicient resiliency to avoid inconvenience in closingthe doorwith the advantage of a firm bearing contact therewith.

A still further object of the invention is to provide a device which maybe very firmly mount ed with the use of a single securing member.

With these and other objects in view the invention consists essentiallyin a resilient pad of substantial wedge-shaped form, the thickness ofwhich is gradually reduced towards one edge to provide a sloped uppersurface terminating in a posite side of the pad being of greaterthickness and terminating in a flat surface designed to abut acorresponding surface of the door frame, the upper surface of the pad,and at least one exposed edge, being covered with a flexible wearresisting material.

,Figure 3 is a similar View to Figure 2, illustrating an alternativeform of covering.

Figure 4 is a fragmentary perspective view 5 partly in section, showingthe device mounted on a door frame and the door in contact therewith inclosed position. i

Referring more particularly to the drawing, A indicates the device as awhole comprising a pad 10 of resilient material, preferably rubber,which is reduced in thickness preferably from the middle towards theouter edge 11 to provide a structure of substantially wedge-shaped form,having a main bearingsurface 12 arranged in a horizontal plane betweenthe middle of the pad and'its inner edgewhich terminates in asubstantially flat surface 13 disposed in a vertical plane. The pad iscovered with a flexible wear resisting material 14; such as thin metal,in such a manner thatfthe upper surface and the outer edge 11 at leastare encased, it being preferable to encase both the outer and inneredgesHand 12 as well as the upper surface.

Theflat edge 13 is designed to abut the vertical plane surface 15 of thedoor frame, as illustrated in Figures 2 and 3, and by mounting the padin this way it may be secured by a single securing member, such as ascrew 16, which projects through suitable orifices 17 and 18 in thecover and the pad respectively and by reason of the fact that, a firmbearing engagement between the side of the door frame and the fiat edge13 of the pad exists, the securing member 16 once placed in positionwill hold the device firmly on its mounting without any danger ofdisplacement. I The covering may be of such form, as illustrated inFigure 2, wherein the pad is recessed the base of the pad may be formedentirely flat throughout its area and thecovering bent thereat 23, themain intention being to provide a covering" for the upper surface andthe front edge and to adopt the typeof covering that is most suitable toprovide a durable, article, which has at least apart or the whole of itsbase encased and thus reinforced, while producing a combination rubberand metal article in the form ofa single unit. 1

By employing: such a construction it will be readily apparent when thedoor is swung to AT NT OFFICE? 1,986,744. ANII ATTLED VI'CE" 7 ItobcrtDart Muxworthy, MedicineHat, lilberta closed position its base willfirst contact with the covering of the outer edge 11 and owing to theshape of the pad and its resiliency the door will be firmly wedgedagainst rattling yet no difiiculty will be experienced in closing thedoor since the construction provides against jamming. The covering willat the same time provide for an easy sliding engagement while beingresistant to wear. For mounting; purposes the covering andzpad arecountersunk in;wel1-,known1 manner, such as shown in U. S. Patent No.1,112,108, to accommodate the securing member. 7

It is obvious, therefore, that I have provided a device of extremelysimple form whichmay be mounted firmly in position with; anminimmn ojefhfort and which will overcome the difficulties referred to.

I claim:- 1. An antirattle device for comprising a unitary memberincluding a resilient" pad; of substantially" wedgershaped form providedwith a flat base to engage with a mounting, said pad having its surfaceopposite to the base and at least one exposed edge covered with a singlepiece of thin flexible wear resisting material following the contour ofthe pad, said material forming a backing for at least a portion of thebase of the pad.

2. An antirattle device for automobile doors comprising a unitarymemberrincluding a resilient padlhavingaflatisurfacedbase; atflat edgeand a smooth surface opposite the base, a portion of .the; lattersurface being sloped from substantially the middle of the pad towardsone edge to provide'a wedge-shaped portion, the said latter surfacevof:the pad,v the fiat edge and the edge opposite thereto and at least aportion of the lower surface being covered with thin flexiblewear-resisting material following the contour of automobile. doors;

the padp and applied in a single piece.
